[PATCH 7/8] i2c: Make I2C_EXYNOS5=y impossible when EXYNOS_USI_V2=m

When HSI2C is encapsulated in USIv2 block (e.g. in Exynos850), USIv2
driver must be loaded first, as it's preparing USI hardware for
particular protocol use. Make it impossible for i2c-exynos5 driver to be
built-in when USIv2 driver is built as a module, to prevent incorrect
booting order for those drivers.
